Planet with water vapour.

On the news tonight. A planet about twice the size of Earth has been found with water vapour in its atmosphere. Its around 100 light years away. Apparently its within the ‘goldilocks’ area around its star so its temperature is between 0°C and 40°C. It would be amazing if there was life there. The latest science is now looking for chemical traces in planetary atmospheres to look for the possibility of life on other planets.

I think the first extra solar planet was found in 1984? Since then about four thousand have been found. There are Hot Jupiter’s that orbit their stars closer than the orbit of Mercury in our solar system. There are cold Jupiter’s, there are also planets like Earth with surfaces that are covered in lava because they are close to their stars. And then there are terrestrial (rocky) planets that are more like the ones in our system.

One thing is certain, there are more planets out there than we know!
